To all whom it may-concern. v I

Be it known that 1, WILLIAM Asoon, a citizen of the United States, resldm at K1-.

Kansas, have invented certain new and use ful Im rovements in Grain-Doors, of which the folidwing is a specification. v i

This invention Is agrain-door for. cars, granaries and'the like, and has for; its object to provide a door which, will effect a grain'-. tight closure, and one which is simple in construction, and can be easily opened and I which are in the doors are slots in which are mounted rollers 21 whereby the doors are slidably closed.

In the accompanying drawing, Figure 1 1s a transverse sectionalview of the door closed. Fig. 2 is ,a similar view showing the door open. Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1. Fig.4 is a horizontal sec- 4 tion on the line 4-4 of Fi 1. Figs. 5, 6, and 7 are details showing t e apparatus for starting the-opening movement of the door. Fig. 8 is adetail showing the door construction.

Referring specificall to the drawings, 10 denotes the floor of a eight car, and 11 are the side wallsthereof having doorways the jambs of which are indicated at 12. I

To the door-j ambs 12 on the inside of the car are secured runways orv tracks 13 and under the roof of the car are continuations of said runways, consisting of channel-beams 14 extending in a curve to the top ends of said runways. The channel-beams 14 are secured to the roof by hangers 15. The runways 13 are provided with a shield'16 hinged to one edgev thereof as indicated at 17 and provided with a pivoted latch 18 for holding the same closed.

The door comprises a series of sheet-metal sections 19 which are connected at their longitudinal ed es by hinges, the pintles of icated at 20. At the ends of mounted on the runways 13 and 14. The

pintles 20 extend across the slots and serve as axles for therollers. The doors and runways are the same on both sides of the car. On the outside of the sections 19 are longitudinal flanges 22 to brace and stiffen the same, and prevent bulging out from the weight of the grain.

'When the doors are closed their outer I edges and the rollers 21 are inclosed by the The doors are opened by sliding them up- .wardly on to the runways 14 which are suowa, in the county of Ba'rberand tate of I I "rattantiinec. 1o, 190+.

' Any-suitable me 'n's employed for elevating the doors. I have shown shafts 23 mounted in bearings at. the top of the doorways- On the shafts are wound cables 24 connected to the top edge of the doors.

Aworm ear 25 is employed for turning the is provided for preventing back slip.

To start the door a liftlng jack is provided which is connected to the outside of the door and is-foldable thereagainst so that it may travel with the door when it is elevated to the runwa 14.

The jac comprises a lever 27 pivoted at 28 to a support 29 which is pivotally mounted in a bracket- 30 secured to the door on the shaft, an a pawl and ratchet mechanism 26 outside thereof The'fulcrum of the lever is a frame comprising two's aced plates .31.

having a toothed slot 32. T e lever extends between the plates and has pins 33 projecting from its sides which are engageable with the teeth of the slot 32. When the jack is not in use, the fulcrum frame is swung around "so that the lever extends therebetween and the jack is then swung against the side of the door as shown in Fig. 7, so as to be out of the way. A catch 34 is provided for holding the jack in this position. When the jack is to be used, it is released from the catch and swung outwardly from the door. The fulcrum frame is then turned and'placed on the floor of the car as shown in Figs. 5 and 6 after which the lever can be operated in an obvious manner. p p

.In the drawings the invention is shown applied to a grain-car but itcan also be applied to granaries, bins, etc., as well as to cars carrying coal or other loose material.-

The doors work easily, are strong and durable, and simple in construction, ,and they a aflord a tight closure.

I claim:

1. The combination with a door -'frame having runways; of a sliding door having rollers at its ends traveling on the runways; and a shield hinged at one edge adjacent the runways and extending in a bend around the rollers, and at its opposite edge in sliding around the rollers, and at its opposite edge eontaetwiththe door; in sliding contact with the door. 10 2 The combination with a door-frame In testimony whereof I afiix my signature,
